Description

Technical Field

[0001] The present application relates to the field of tires, and in particular to a structure capable of enhancing the deformation resistance of a tire tread. Background Art

[0002] Tires are circular elastic rubber products that roll on the ground and are installed on various vehicles or machines. They are usually installed on metal rims, can support the vehicle body, buffer external impacts, achieve contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions. They are subjected to various deformations, loads, forces, and high and low temperature effects when driving, so they must have high load-bearing performance, traction performance, and buffering performance. At the same time, they are also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation.

[0003] like Figure 1 As shown, the structure of the existing tire is that the edge of the first belt layer 3 is covered with a first belt layer cushion rubber 5 of a certain width. The advantage is that the possibility of the first belt layer delamination due to repeated flexion movement and heat generation is reduced. The disadvantage is that the two ends of the first belt layer are not covered with rubber, the steel wire is exposed, and it is not easy to compact and there are gaps during the production process. During the long-term use of the tire, this position is weak, and the steel wire is easy to pierce the tread. In more serious cases, the tread will deform and fall off. Utility Model Content

[0004] In order to make up for the above shortcomings, the present application provides a structure that can enhance the deformation resistance of the tire tread, aiming to improve the problem that the two ends of the first belt layer are not covered with rubber, the steel wire is exposed, and it is not easy to compact and gaps appear during the production process. During the long-term use of the tire, this position is weak and the steel wire is prone to piercing the tread. In more serious cases, the tread may deform or fall off.

[0005] An embodiment of the present application provides a structure capable of enhancing the deformation resistance of a tire tread, including a tread.

[0006] A first belt layer is provided on the inner side of the tread extending to the shoulder, a cap layer is provided between the first belt layer and the tread at the shoulder, the upper and lower sides of the first belt layer at the shoulder are wrapped with rubber strips, and the rubber strip is one, which is first wrapped from the top of the first belt layer, bypasses the side of the first belt layer, and wraps the bottom of the first belt layer.

[0007] In a specific embodiment, the width of the adhesive strip is 24.9 mm-25.1 mm, and the thickness of the adhesive strip is 0.4 mm-1.1 mm.

[0008] In a specific embodiment, the wrapping length of the rubber strip above the first belt layer is 13 mm.

[0009] In a specific embodiment, the wrapping length of the rubber strip below the first belt layer is shorter than the wrapping length of the rubber strip above the first belt layer.

[0010] In a specific embodiment, a cord fabric is disposed on the inner side of the first belt layer.

[0011] In a specific embodiment, an airtight layer is provided on the inner side of the cord.

[0012] Beneficial effect: In the process of preparing the semi-components, the edge of the first belt layer is wrapped with a rubber strip to avoid exposure of the steel wire, and the risk of false pressing in the production process can be prevented, and damage can be prevented from occurring at this position, making the pressing tighter and increasing the service life of the tire. And during production, if necessary, the second belt layer can also be covered with rubber at the same time. The utility model wraps the first belt layer with a rubber strip, which can effectively reduce the probability of steel wire puncture and tread deformation and damage in the first belt layer, making the tire safer to use and increasing the service life of the tire to a certain extent.

[0018] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0019] See also Figure 1-Figure 3 The present application provides a structure capable of enhancing the deformation resistance of a tire tread, including a tread 1.

[0020] See also Figure 2 and Figure 3 , a first belt layer 3 is arranged on the inner side of the tread 1 extending to the shoulder, a cap layer 2 is arranged between the first belt layer 3 and the tread 1 at the shoulder, and the upper and lower sides of the first belt layer 3 at the shoulder are wrapped with rubber strips 7, and the rubber strip 7 is one, which is first wrapped from the top of the first belt layer 3, bypassing the side of the first belt layer 3 and wrapping the bottom of the first belt layer 3. In the process of preparing the semi-components, the edge of the first belt layer 3 is wrapped with the rubber strip 7 to avoid the exposure of the steel wire, and can prevent the risk of false pressing in the production process, prevent damage from starting at this position, make the pressing more compact, and increase the service life of the tire. And during production, if necessary, the second belt layer can also be coated with rubber at the same time. The utility model wraps the first belt layer 3 with the rubber strip 7, which can effectively reduce the probability of steel wire piercing the first belt layer 3 and deformation and damage of the tread 1, making the tire safer to use and increasing the service life of the tire to a certain extent.

[0021] In this embodiment, the width of the rubber strip 7 is 24.9 mm-25.1 mm, and the thickness of the rubber strip 7 is 0.4 mm-1.1 mm. When the semi-finished product is prepared, the rubber strip with a width of 25 mm and a thickness of 1 mm is cut into pieces according to the following steps: Figure 3 As shown, the rubber strip 7 is wrapped around the edge of the first belt layer 3 and is subsequently used as a whole half. The rubber strip 7 is not easy to be too thick, which is not convenient for the overall production of the tire in the later stage.

[0022] In a specific configuration, the wrapping length of the rubber strip 7 above the first belt layer 3 is 13 mm. The wrapping length of the rubber strip 7 below the first belt layer 3 is shorter than the wrapping length of the rubber strip 7 above the first belt layer 3. The rubber wrapping protection of the first belt layer 3 is achieved, thereby preventing the steel wire from being exposed and increasing the service life of the tire.

[0023] In this embodiment, a cord 4 is provided on the inner side of the first belt layer 3. An airtight layer 6 is provided on the inner side of the cord 4.

And during production, if necessary, the second belt layer can also be coated with rubber at the same time. The utility model wraps the first belt layer 3 with a rubber strip 7, which can effectively reduce the probability of steel wire puncture of the first belt layer 3 and deformation and damage of the tread 1, making the tire safer to use and increasing the service life of the tire to a certain extent.
